Wow: it's been quite a while — not since The Big Dig in July.
Anyway, the reason I've been away is this:
Sometime in early 2010, I hatched a plan to build a vehicle that I would transport to Winnemucca, Nevada then pedal 100 miles to Burning Man. I knew time was too short to make it for that year, so I slated it for 2011. Well, I spent hundreds of hours on design toward the beginning of the year, a dollar amount I'm afraid to calculate on custom-designed parts as well as off-the-shelf parts, and another hundreds-of-hours on building. By Sunday, August 7, I did not yet have a pedal-able vehicle, and I had 11 days before I would need to ship it, so I put it off for another year.
The more precise plan was to ship the trike to Winnemucca by UPS Ground. I have designed it so it folds up and can be shipped in a relatively small crate (which doubles as a trailer for extra gear). I would take the train to Winnemucca and it would hopefully be waiting at the hotel — probably Scott Shady Court Motel (400 1st St., Winnemucca, NV) which I stayed at and liked a lot before. Sunday, the day before Burning Man starts (on Monday), I'd get my water jugs filled, get packed up, and head for Jungo Road (a.k.a. Nevada SR 49). From there I'd pedal the 85 miles to 40° 46' 02.07" N, 119° 07' 12.26"W where there is a microwave antenna access road that crosses the railroad tracks. I would hope to pass the active mine at Sulphur before nightfall as there's a bit of traffic supporting it (not so much on Sunday, but on the way back). I'd take a right and cross the tracks then head due west across the Black Rock Desert, north of the Burning Man event, until I reach the barely-marked West Playa Highway which I'd take south to the main gate. After the event, I'd just reverse the trip. I estimate about 100 miles each way which could take anywhere from 10 to 24 hours depending on how fast I could go — and since I haven't tested anything yet, I really have no idea what is practical.
The vehicle itself is called a "tadpole trike" because it has three wheels and kind of looks like a tadpole with 2 wheels in front for steering and one rear wheel for propulsion. The picture shows the frame as far as I had completed it, and nearest the photographer is the mount for the pedals. I used parts from the 1994 Honda Civic I had taken off the road 2 years ago, parts from go-kart companies, bicycle parts, lots of scrap metal (mostly from bed frames), and the final drive is to use motorcycle chain for extra strength. I estimate that including the tires, it will weigh in slightly less than 200 pounds, so it's definitely not meant to win any hill-climbs.
But I did design it with a broad gearing range: a 2-speed custom shifter doubles the range of a continuous-variable Fallbrook NuVinci 360 internal hub shifter from a stump-pulling 0.2-to-1 to a mountain-bike-high-gear 3.5-to-1. In terms of gear-inches (which, if you imagine a pennyfarthing big-front-wheel bike, it's the effective diameter of that wheel) it has a range of 5.2 gear-inches to 18.2 gear-inches in low and 22.9 to 80.0 gear-inches in high. So with a pedaling speed range of 15 rpm to 150 rpm, that translates, overall, to 0.23 mph to 35 mph. And assuming I can put a maximum of 300 pounds of force on the pedal at a standstill, the lowest gearing will yield a massive 800 pounds of forward-force at the drive wheel.
I figure my goal is to just attempt it. If I have to stop and go back, or haul the beast back broken, then so be it. The road itself is generally pretty obvious, but I do have USGS topographic maps of the whole area along with a compass and a GPS for good measure. I set up JayceLand to be able to accept picture-message posts like I did for the Big Dig … Verizon's map shows the last point of "coverage" to be around 40° 53' 21.534" N, 118° 26' 15.342" W which is little more than halfway, and not quite to Sulphur.
But alas, the whole idea seems to be quite distant now. Funny how a week ago I was picturing it actually happening, and now I don't even know if I'll try it in 2012 — or ever for that matter. I think I will desire it again in the future. After all, part of the beauty of it is that I can potentially be someplace where it's more than 20 miles to the nearest person. The whole trike and its testing is a separately interesting matter, but I can get that accomplished with some camping trips around here, or even just using it as a main vehicle.
We shall see!
